To address the challenges of the consumer wireless device industry, we have designed a dynamically reconfigurable architecture with flexibility limited to address the MAC layer. It is a Software/Hardware partitioned platform in which critical tasks are delegated to a dynamically reconfigurable hardware co-processor. It will handle data streams of multiple (up to 3) different protocol standards, by reconfiguring on a packet-by-packet basis. The Interface and Reconfiguration Controller uses a combination of controllers to dynamically reconfigure the functional units in the architecture and delegate MAC tasks to them. Results of packet transmission on a prototype model indicate that the device handles three transmission requests from different protocol modes in a fraction of the packet durations.
